Scores
AI judge
Not scored
No rubric for this prompt
Visitor votes and reviewer grades are not available yet.
- AI judge
- AI judge: the test runner (model claude-opus-5-5), scoring by visual review of the 1600 px render against the pre-registered rubric. No AI-judge score exists for this result: there is no rubric for this prompt, so no score is shown and none is made up.
- Visitors
- Public voting with a blind reveal is coming: you score the output first, then see the other scores.
- Reviewer
- The reviewer's own grade appears here once it is added.
Scores compare results for the same prompt only. AI-judge boards rank runs within one prompt, equal totals sharing a rank; scores from different prompts are never averaged.
Downloads
Files actually published for this run. Original output, site-made previews and post-run conversions are labelled separately.
The exact prompt
as run, 358 characters. Every result for this prompt
Create an SVG illustration of a messaging app screen with alternating grey and blue speech bubbles, a timestamp, a typing indicator and a text input bar with a send button. Save it as image.svg in the current directory. You may render and inspect your own output (headless chromium is available at /usr/bin/chromium) and iterate on your own before finishing.
How it was made
Versions saved during the run
3 intermediate outputs, in the order the model wrote them.
Step by step
The prompt, every agent turn and tool call (tool name and a one-line summary; inputs and outputs are not shown), then the final message. The full machine-format transcript is published as a scrubbed download.

Cost breakdown
Headline cost $0, as reported by OpenCode (its own bill for the run).
| Tokens by type | Tokens | $ per 1M | Cost |
|---|---|---|---|
| Input (uncached) | 36,168 | n/a | n/a |
| Cache write | 0 | n/a | n/a |
| Cache read | 430,336 | n/a | n/a |
| Output | 17,313 | n/a | n/a |
- Total computed from tokens
- unknown
- Total reported by the harness
- $0
OpenCode 1.18.32 reported its own total; token counts x list prices shown beside it. No list price for longcat-2.5-preview-free in config/prices.json; no estimate computed. The harness reports reasoning tokens separately from output; here output includes them (8,820 visible + 8,493 reasoning), and both bill at the output rate.
Run notes
- frozen prompt (written): our frozen prompt, suite svg_250 (harness variant of svg_chat_interface)
- plain OpenCode config copy (providers only; no ECC instructions/agents)
- opencode export written to a file (not piped)
- Mode: interactive TUI in tmux (160x48), inside bubblewrap sandbox
- Isolation audit: outside paths seen
